Impact of Hearing Loss<\/strong>
Hearing loss doesn\u2019t just affect humans. Whales, dolphins and bats are known for utilizing sound as not only a form of communication but also to help them move around. The Washington Post recently discussed a study<\/a> that shows hearing loss and interference as a serious problem for whales. An interfering noise at the right frequency or a loss of hearing can leave whales distressed, lost and possibly even unable to hunt for food. The same goes for dolphins. Proposed seismic testing in Taranaki\u2019s Marine Mammal Sanctuary for oil could lead to permanently damaging the hearing of whales and dolphins both within and near the sanctuary. \u201cBecause dolphins navigate with sound it would be the equivalent of blinding a human,\u201d one source stated.<\/p>\n\n\n\n

Sense of Hearing<\/strong>
Clues about the origin and evolution of the sense of hearing can be found in a creature from the depths of the ocean \u2013 the squid. Until recently, little was known about how well a squid could hear; whether or not they relied on hearing to navigate, to sense danger or avoid marine predators. A 2012 study<\/a> on the hearing and neuroanatomy of squid showcased many similarities between the hearing systems of squid and humans.
By testing how sensitive squid are to sounds and looking at their frequency range, we are able to use squid \u201cears\u201d and hair cells as models for examining human hearing.<\/p>\n\n\n\n

Noise Reduction<\/strong>
Step back onto land, and you\u2019ll hear the persistent chirping of the Zebra finch. Researchers have long been interested in the male songbird\u2019s complex vocalizations used during courtship, but a recent study<\/a> revealed how finch brains recognize these vocalizations in noisy environments.<\/p>\n\n\n\n

The finch\u2019s ability to respond to birdsongs and ignore everything else is similar to our own ability to recognize speech in a noisy environment. This finding led primary researcher Fr\u00e9d\u00e9ric Theunissen, Ph.D. and graduate student Tyler Lee to generating a computer algorithm designed to help reduce noise, which could help fine-tune hearing aids to better extract speech from noise.<\/p>\n\n\n\n

In 2009, we tested the effects of noise reduction using an algorithm similar to Theunisssen and Lee\u2019s and found an unexpected benefit. While noise reduction doesn\u2019t make speech more understandable, it does reduce the brainpower required to process it. For someone who has trouble hearing in noisy environments, this finding can mean the difference between being part of the conversation or checking out of it.<\/p>\n\n\n\n

Hearing Aid Technologies<\/strong>
Earth also provides us with natural elements to model our hearing aid technologies after.<\/p>\n\n\n\n

On a lotus plant, water droplets form spheres and completely roll off the leaves, carrying dirt with them. Known as the Lotus Effect, this self-cleaning practice is the model for the protective hearing aid coatings, HydraShield 2 and Surface NanoShield on our NuEar hearing aids. Exposure to moisture, wax, oil and other liquids is one of the most common problems hearing aids face. Used on the receivers, battery doors and microphone covers of our hearing aids, these coatings provide resistance against these substances to help prolong hearing aid performance and help reduce hearing aid repairs.<\/p>\n\n\n\n

With clues about the origin of the sense of hearing, animals who help us better understand how noise reduction works and natural elements that we can look to for innovation, Earth is helping achieve better hearing every day. It gives us the tools and resources we need to manufacture and deliver advanced hearing solutions, bring people together and ultimately enrich the lives of individuals with hearing loss.<\/p>\n","protected":false},"excerpt":{"rendered":"
